The effect of aluminium chloride, quercetin, and lipoic acid treatment on acetylcholine esterase activity in the brain of rats. Enzyme activity is expressed as nmoles of substrate hydrolyzed min⁻¹mg protein⁻¹ in the brain of rats. ^∗∗∗Significant as compared to control group of rats (p < 0.001). ^∗∗Significant as compared to control group of rats (p < 0.01). ^∗Significant as compared to control group of rats (p < 0.05). ^@@@Significant as compared to AlCl₃ treated group of rats (p < 0.001). Comparison between the groups was done using Dunnett's multiple comparison test.
